WordPress では、サイトの所有者が各ユーザーに対してサイト内で利用できる機能を管理するための「権限グループ」という概念を使用します。サイトの所有者は権限グループに各ユーザーを含めることでタスクへのアクセス権を管理できます。タスクには投稿の作成と編集、固定ページの作成、カテゴリーの作成、コメントのモデレート、プラグインの管理、テーマの管理、他のユーザーの管理 などがあります。
WordPress にはあらかじめ定義された6個の権限グループがあります。特権管理者、管理者、編集者、投稿者、寄稿者、購読者です。各権限グループのユーザーには、「権限」と呼ばれる一連のタスクの実行が許可されています。権限には “publish_posts”、“moderate_comments”、“edit_users” を含む多くの種類があります。権限グループにはあらかじめデフォルトの権限が設定されていますが、add_cap() 関数や remove_cap() 関数を使用して他の権限を付与または削除することもできます。add_role() 関数や remove_role() 関数を使用すると、新しい権限グループを導入または削除できます。
「特権管理者」権限グループに所属するユーザーはすべての権限を実行できます。他の各権限グループは、それぞれ制限された実行可能権限を持ちます。たとえば、「購読者」権限グループは “read” 権限のみを持っています。ある権限グループが、他の権限グループの上位に位置すると考えるべきではありません。むしろ、権限グループはサイトにおけるユーザーの責任を定義するものと考えてください。
権限グループの概要 権限グループの概要
- 特権管理者 – サイトネットワーク管理機能や他のすべての機能へアクセスできるユーザー。「ネットワークの作成」を参照してください。
- 管理者 (スラッグ: ‘administrator’) – シングルサイト内のすべての管理機能にアクセスできるユーザー。
- 編集者 (スラッグ: ‘editor’) – 他のユーザーの投稿を含むすべての投稿を公開、管理できるユーザー。
- 投稿者 (スラッグ: ‘author’) – 自身の投稿を公開、管理できるユーザー。
- 寄稿者 (スラッグ: ‘contributor’) – 自身の投稿を編集・管理できるが、公開はできないユーザー。
- 購読者 (スラッグ: ‘subscriber’) – プロフィール管理のみを実行できるユーザー。
WordPress をインストールすると、すべての権限を持つ「管理者」アカウントが自動的に作成されます。
新規ユーザーのデフォルトの権限グループを設定するには、管理画面 > 設定 > 一般設定を実行します。

権限グループには、ユーザーに与えた一連のタスクの実行許可が定義されています。たとえば、「特権管理者」権限グループは、仮想WordPressサイトのネットワーク内で実行可能なすべてのタスクが含まれています。「管理者」権限グループは、許可されるタスクをシングルサイトに影響を与えるタスクだけに限定します。その一方で、「投稿者」権限グループは、ほんのわずかにすぎない部分的なタスクの実行を許可します。
下記のセクションでは、デフォルトの権限グループとその機能を載せています。
Super Admin Super Admin
Multisite Super Admins have, by default, all capabilities. The following Multisite-only capabilities are therefore only available to Super Admins:
- create_sites
- delete_sites
- manage_network
- manage_sites
- manage_network_users
- manage_network_plugins
- manage_network_themes
- manage_network_options
- upgrade_network
- setup_network
In the case of single site WordPress installation, Administrators are, in effect, Super Admins. As such, they are the only ones to have access to additional admin capabilities.

Special Cases Special Cases
The following capabilities are special cases:
- unfiltered_upload – This capability is not available to any role by default (including Super Admins). The capability needs to be enabled by defining the following constant:
define( 'ALLOW_UNFILTERED_UPLOADS', true );
With this constant defined, all roles on a single site install can be given the unfiltered_upload capability, but only Super Admins can be given the capability on a Multisite install.
